E101 Cat I Float-Free HRU Hammar H20

Ocean Signal E101 Cat I Float-Free HRU Hammar H20 is identified in the source list as a epirb (406 mhz) category i. It is stowed, mounted or worn at the emergency location appropriate to the approved beacon or transponder type so it can be activated or released as intended. Its purpose is to support distress alerting, survivor location or search-and-rescue detection according to the radio service identified by the category. The source record provides no additional model-specific operating figure beyond the listed designation and category. Activation method, antenna arrangement, GNSS capability, float-free release and transmitted identity depend on the exact approved model. The exact model designation distinguishes radio function, activation arrangement and certification from neighboring emergency beacons or transponders; refer to the manufacturer documentation for the exact figure.
